In a long - term character development arc, Alucard and Anderson could end up becoming friends or at least having a mutual respect that extends beyond their initial enmity. They could learn from each other's strengths and weaknesses. For example, Anderson could teach Alucard about the value of faith in a different way, while Alucard could show Anderson the power of acceptance of one's darker side.
Alucard could start to see Anderson not just as an enemy but as a worthy adversary with a sense of honor. This might make him less bloodthirsty towards Anderson specifically. For Anderson, he might come to understand that Alucard is not just a mindless monster but has his own reasons and a complex past.
Anderson might become more lenient in his views of vampires in general due to his interactions with Alucard. Alucard, on the other hand, could develop a sense of camaraderie with Anderson, something he hasn't had with a human in a long time. This could lead to him protecting Anderson in certain situations, which is a big change from his usual attitude.
For Alucard, his determination is a great trait. No matter how difficult the situation, he never gives up. In fanfiction, this can lead to some really intense showdowns. Anderson, on the other hand, has his unwavering faith. It gives him strength and makes him a formidable opponent.

Joey could start as a timid trainer and become more confident as he bonds with Rattata. Rattata, on the other hand, might start off as a wild and skittish Pokémon but become more loyal to Joey over time.
Karai could start off as a cold and calculating character, but as she spends time with April, she might become more empathetic. For example, seeing April's kindness towards others could make Karai question her own actions.
Pikachu might become more empathetic. Usually, Pikachu is known for his energy and courage. But in a fanfic with Buneary, he could learn to understand Buneary's more delicate feelings. For instance, if Buneary is sad because she misses her family, Pikachu could learn to comfort her in his own way, which would make him more in - touch with emotions.
For Hanamiya, he could start as a very antagonistic character, but as he spends more time with Kuroko, he might become more empathetic. For example, he could learn to understand the importance of teamwork in a more positive sense, rather than just using his teammates as tools to win.
A common theme is the battle of ideologies. Anderson, being a devout Catholic and Alucard, a vampire, they have very different outlooks on life and death. Fanfictions often explore how these clashing beliefs interact when they face each other.
In the fanfic, Fresh might learn to respect boundaries more. His wild nature sometimes means he oversteps. But with Paper Jam, who has clear boundaries, he'll have to adjust. This will make him a more well - rounded character. For Paper Jam, he could develop a sense of humor. He's quite serious, but Fresh's antics can start to crack his serious exterior and he'll start to see the fun in things, which will completely change his personality for the better.
They could both develop a deeper bond of friendship. Through shared experiences like helping out at a local animal shelter or solving a mystery in their neighborhood, they would trust each other more. This would lead to them being more comfortable around each other and being able to communicate without words in some situations.
Both of them could learn about the importance of individuality. Pikachu might realize that being different like Mimikyu is not a bad thing, and Mimikyu could understand that it doesn't have to be exactly like Pikachu to be accepted. They could both grow to appreciate their own unique qualities as well as those of each other.
